Python 使用keras但得到错误AttributeError:'；张量'；对象没有属性'_keras#u历史'；

我目前正在使用keras实现自动编码器，以便对图像进行上采样

我想用相邻图像的信息来创建一个上采样的中心图像。垂直和水平邻域都应该共享编码器中的权重。在瓶颈处，将垂直和水平图像块连接起来并开始解码

代码如下：

learning_rate = 0.0001
adam = keras.optimizers.Adam(lr=learning_rate)
batch = 20
epoch = 5000
SR_Autoencoder = Model(inputs=[input_LF_v, input_LF_h], outputs = decoded_vh_up5)

SR_Autoencoder.compile(optimizer = adam, loss = 'mse')

SR_Autoencoder.fit([stack_v,stack_h], cv, batch_size = batch, epochs = epoch, validation_split = 0.1, shuffle = True)

当我尝试运行它时，收到错误消息：

谁能告诉我哪里错了吗

提前谢谢

每个操作都必须由“keras层”执行，不可能在其外部进行操作

decoded_vh_up = Lambda(lambda x: K.concatenate(
    [x[:,0,:,:,:],x[:,1,:,:,:],x[:,2,:,:,:],x[:,3,:,:,:],x[:,4,:,:,:]]
))(decoded_up1)

显然这里有人有办法。当然可以，但我已经检查了我的代码，只有keras层，没有其他操作。我也是使用keras的初学者。此时此刻，我找不到这里提到的任何类似的错误。
